I still think MacArthur himself tends to the hyperbole (using charitable terms here). He is the CEO of a virtual Home Depot full of broad brushes. He too needs to be interpreted :-).
MacArthur is pretty staunch as well...though understandably why that is. I agree that any who preach and teach need to be examined in ones own time with the Lord for verification on disputable matters. Sometimes it takes time before the Lord makes that clear....
....but in the end He has never failed me in understanding His Word and will when it matters I do.
